Fetal movement will usually be felt regularly after the 20th week of pregnancy. Any change in fetal movement (other than a 1-2 hour sleep cycle that some fetuses have) should be discussed with your physician. Decreased or absent fetal movement may be a sign of fetal distress. Kick tests (fetal movement counts) are used to monitor fetal wellbeing. You should monitor fetal movements (not just kicks) over a period of time (30-60 minutes). There is no right or wrong number of movements. You are trying to establish a baseline of fetal movements for your baby.
What you may mistake for a heartbeat could be your baby's hiccups or kicks. According to BabyCenter, you may feel your baby's hiccups late in the second semester.
